8 Claims.

This invention relates to a device for successively feeding disks, or the 1ike,'and is particularly directed to a device for feeding disk seals 7 or covers into position upon receptacles to be covered. The invention will be fully understood from the following description taken in connection with the accompanying drawings, in which latter Fig. 1 is a side elevation of the device;

Fig. 2 is a front elevation of the device;

Fig. 3 is a detail showing in front elevation the discharging mechanism;

Fig. 4 is a perspective view of the lower porr tion of the magazine looking along the line IV-IV of Fig. 3;

Fig. 5 is a front elevation of a detail of a modified form of the device;

Fig. 6 is a side elevation of the construction shown in Fig. 1; and

r Fig. 7 is a perspective view of the lower portion of the magazine looking along the line VIL-VII of Fig. 5.

Referring to Figs. 1, 2 and 3 of the drawings, reference numeral 1 designates a trough through which disks 1 in a row are adapted to be fed manually, or in any other suitable manner, to the inlet opening of a magazine 2. The magarzine contains a slot extending throughout its length which is adapted. to receive the disks for 30 sliding movement in edge to edge relation. The

disks are disposed in a column in the magazine.

A disk pusher is provided for successively forcing the disks from the trough into the magazine.

r The disk pusher comprises a body portion 3 which is mounted for pivotal movement at 4. A projection 5 extends outwardly from the body portion and is adapted to engage the disks. A suit- ;able handle 6 is provided which can be manually engaged to operate the disk pusher. f7

project outwardly from the magazine and form a guideway for the disk pusher. The disk pusher :can be pivoted rearwardly to the position shown in dotted lines in Fig. 1.

The disk at the bottom of the magazine is sup- 45 ported in position by a disk retainer 8 which cooperates with a wall having shouldered portions 10'. The wall 9 of the magazine at the right hand side of the slot, as viewed in Fig. 3, terminates above the opposite wall 10 of the mag- Q azine. The disk retainer is pivoted to the wall 9 at 11 so that the bottom of the retainer can swing outwardly to the right as viewed in Fig. 3. The bottom disk is supported with a portion thereof I" projecting downwardly below the wall 10. A curved picker 12 is carried rigidly upon the back the opposite Wall 10 of the magazine.

of the disk retainer and is adapted to project through an opening 13 in wall 9 into position to be engaged by the lower edge of the next to the bottom disk and support the disk when the disk retainer is pivoted outwardly. A spring 14 associated with wall 9 engages the disk retainer to normally maintain the retainer in position to press the disk against the Wall 10 thereby supporting the bottom disk. Upon return of the disk retainer to its normal position, therpicker 12 disengages the next to the bottom disk.

. The disks are constructed with turned under edges as can be seen in Fig. 3. The disks are fed into the trough 1 with the turned under edges facing the magazine so that the underside of the bottom disk is exposed for engagement by a nozzle on can 15 or other receptacle to which the cover is applied. Cans 15 are fed into position to receive the covers by means of a travelling conveyor 16. The cans travel in a left to right direction, as viewed in Figs. 2 and 3, and the mouth of each can en ages the projecting under surface of the lower disk behind the turned over edge. Further travel of the can forces the disk retainer outwardly about its axis until the disk can clear the bottom of the magazine and fall into position over the mouth of the can. As the can passes from under the disk retainer, the latter is forced back into its vertical position and another disk is dropped into position to be engaged by the next succeeding can. t

In the modified form of the device illustrated in Figs. 4 to 7, the disk 1 at the bottom of the maga zine is supported in position by a disk retainer which cooperates with wall 10 of the magazine. The wall 9 of the magazine at the right hand side of the slot as viewed in Fig. 5 terminates above The bottom disk is supported with a portion projecting downwardly below wall 10. The disk retainer is pivoted at 21 to a member 22 carried by the wall 9 of the magazine so that the lower portion of the disk retainer can swing outwardly to the right as viewed in Fig.- 5. An arm 23 is pivotally associated at 21 with the member 22. This arm carries a picker 24 which is adapted to projectthrough an opening 25 in wall 9 into engagement with the next to the bottom disk when the disk retainer is pivoted outwardly. The arm 23 is provided with a slot 26 which is engaged slidably by a pin 27 carried by the disk retainer 20. When the disk retainer is pivoted outwardly, the pin 27 is moved upward in slot 26 permitting a spring 28 to elevate the arm 23 and cause the picker 24 to yieldingly engage the next to the bottom disk.

When the bottom disk has been released, the disk retainer falls back to its normal position as shown in Fig. 5 due to its own weight. As the disk retainer returns to its normal position, it causes pin 27 to engage the base of slot 26 and move arm 23 downwardly with the result that the picker is caused to disengage the next to the bottom disk. This disk then falls to the bottom position as shown in Fig. 5 where it is held.

Various changes may be made within the scope of the appended claims in which it is desired to claim all novelty inherent in the invention as broadly as the prior art permits.

I claim:

1. A disk feeding device, comprising a magazine adapted to contain a column of disks in edge to edge relation, a retainer cooperating with a sidewall of the magazine to support the bottom disk in substantially vertical position, the retainer being adapted to be moved laterally with the disk from the wall to let fall the disk in a substantially horizontal position, means associated with the retainer and operated thereby to engage and hold the next to the bottom disk upon said movement of the retainer, and means adapted to normally hold the retainer in its initial position.

2. A disk feeding device, comprising a magazine adapted to contain a column of disks in edge to edge relation and extending downwardly to a discharge opening, a retainer cooperating with a sidewall of the magazine to support the bottom disk, the retainer being pivoted for movement outwardly from the wall to let fall the bottom disk, the magazine having an opening above the retainer, means carried by the retainer and operated thereby to project into the opening to engage and hold the next to the bottom disk in position upon said movement of the retainer, and. means adapted to normally hold the retainer in its initial position.

3.
